Data collection is not about basing all information of merit giving in all accounts here in bitcointalk.org so stop asking why I am not receiving merits base on this report, are you stupid or something?
Data collection is collection of information based only on what's is available, like this data, perhaps he uses only 1000 accounts per rank or per categories to come up with the results, that's why it's not 100% percent accurate. But it is true.
